Class 9 (2) An armament-firing control system comprises an electrically driven switch 12 for supplying pulses to fire projectiles, a second electrically driven switch 11 supplying pulses to drive the first switch and a manual control 13 for the electrical supply to this second switch. The control system is suitable for use on an aircraft and includes provision for bomb release. To fire one, two or three pairs of projectiles the switch 13 is set to cover one, two or three contacts 16, then, if a master switch 22 is closed, a button 30 is pressed to fire the selected number of projectiles. Button 30 causes contacts 26 to latch closed, causing a motor 35, 36 to rotate the switch 11 once thereby delivering the selected number of pulses through contacts 17, 16 to drive the firing switch 12 by a solenoid 41, and at the same time delivering pulses to the projectiles associated with each contact closed by the switch 12. After one revolution of the switch 11 the latch contacts 26 are opened by a coil 28 unless the button 30 is still depressed, in which case the coil 35 remains energized, thereby halting the switch unless a switch 46, normally closed, is open to permit continuous fire. A switch 47, rotating With 12, returns the latter to zero position when a button 54 is pressed. A further switch 60, anually rotated with 13, provides positions opposite contacts 71, 72 for closing a practice bomb circuit or for releasing a bomb, when button 30 is closed.

Excessive speed of a hoist motor coupled to an overhauling load is prevented by means of a differential gear one input shaft of which is driven by the hoist motor whilst the other input shaft is driven by a parallel-connected constantspeed motor. The third element of the differential operates a two-way switch which opens the circuit of both motors when the third element changes its direction of rotation due to the hoist motor exceeding a predetermined speed. A push-button control system for two induction motors having a common shaft and driving a double-skip hoist is referred to. The two-way switch is effective for both directions of operation of the hoist and controls the main contactors in series with the hoist motors and the constant-speed motor. A number of the control relays are supplied at reduced voltage through a transformer, Fig. 2 (not shown). In a modification, the variable-speed motor is disconnected from its power source upon reaching a minimum speed at the lower end of a speed range.
